Gore, Ware Shoais, S.C., assignor to Riegel Textiie Corporation, a corporation of Delaware Filed Jane 26, 1964, Ser. No. 378,207 3 Claims. (Ci. 118-411) This invention relates to apparatus for 'striping a longitudinally traveling web of base material and more particularly to improved apparatus for applying stripes of different colors Without intermixing of the colors in the stripes.

Apparatus has theretofore been available for applying stripes to a base fabric, as exemplified in my prior U.S. Patents Nos. 3,052,211 and 3,064,621. The first mentioned of these patents discloses apparatus for applying stripes to a base material, but does not have any provision therein for applying stripes of different colors without intermixing of the colors. The latter above mentioned patent discloses apparatus for applying stripes to a base material in combination With apparatus for oscillating the base material to provide an oscillating configuration in the stripe. The latter patent also provides for applying stripes of different colors to the base material. However, it has been found that some intermixing of the colors occurs in the apparatus of the latter mentioned patent which is objectionable to the manufacturer and to the user.

Accordingly, it is an object of this invention to provide improved apparatus for applying stripes of different characteristics or colors to a base material without intermixing of the different striping materials.

A further object of this invention is to provide improved apparatus for applying stripes of different characteristics or colors to a base material which separates the different striping materials from the entry of the striping materials into the apparatus to the discharge of the striping materials in stripes on the base material.

A more specific object of this invention is to provide improved striping apparatus comprising separate compartments formed on the stationary frame of the apparatus, separate ducts formed in the stationary frame of the apparatus leading from each of the compartments, feeding and pumping rolls associated with each of the compartments and the ducts for feeding and pumping striping materials from the compartments through the ducts without intermixing of the striping materials, and a nozzle member carried by the frame of the apparatus having a plurality of separate orifices therein communicating with each of the ducts for applying stripes into the base material without intermixing of the striping materials contained in each of the compartments.

Further features of this invention Will become more readily apparent when considered with the following more detailed description taken in conjunction with the accompanying drawings in which:

FIGURE 1 is a perspective view of the striping apparatus of this invention illustrating stripes being applied to a web of material;

FIGURE 2 is a cross-sectional view of the Web of material with the stripes thereon;

FIGURE 7 is a partial perspective view of the nozzle member.

Referring now to the drawings, the striping apparatus of this invention is generally referred to by the reference numeral 111 and is adapted to apply stripes S to a traveling web of material M. The striping apparatus 10 comprises a stationary frame 11 including a central portion 12 extending transversely across the width of the traveling web of material M and end portions 13 and 14. The end portions 13 and 14 have openings 15 and slots 16 formed theretherein, as may be seen in FIGURES 4, 5 and 6. It is noted that the end portion 14 is constructed the same as or complementary with the end portion 13.

The striping apparatus 10 further includes a plurality of feeding and pumping rolls 17. These rolls 17 have end portions 20 which extend through openings 15 in the end portions 13 `and 14 of frame 11 and are thereby rotatably carried by the stationary frame 11 of the striping apparatus. Plates 21, as shown in FIGURES 1 and 6, are carried in slots 16 in the end portions 13 and 14 of the stationary frame 11. The rolls 17, plates 21 and the central portion 12 of the stationary frame 11 forms separate compartments 22, 23, 24 and 25, as may be seen in FIGURES 1 and 6. The compartments 22, 23, 24 and 25 are separated from each other and are adapted to receive different colors of striping material without intermixing of the striping materials in each compartment.

Each of the compartments 22, 23, 24 and 25 has a plurality of separate ducts leading therefrom and formed in the central portion 12 of the stationary frame 11. As may be seen in FIGURES 4, 5 and 6, the compartment 22 has a plurality of ducts 26 leading therefrom, the coinpartment 23 has a plurality of ducts 27 leading therefrom, the compartment 24 has a plurality of ducts 30 leading therefrom, and the compartment 25 has a plurality of ducts 31 leading therefrom. These ducts 26, 27, 30 and 31 are adapted to receive and pass therethrough the striping material contained in each of the compartments 22, 23, 24 and 25 without intermixing of the striping materials in each of the compartments. The ducts 26, 27, 31) and 31 lead to the bottom of the central portion 12 of the stationary frame 11 Where they communicate with separate flared openings 32 formed in the bottom of the central portion 12.

Secured to the bottom of the central portion 12 of stationary.4 frame 11 and extending transversely of the entire width of the traveling Web of material M is a nozzle member 33. This nozzle member 33 has a plurality of apertures 34 therein, separate ones of Which communicate With each of the flared openings 32 so that a plurality of stripes may be applied to `a web of material M from the striping material contained in each of the compartments 22, 23, 24 and 25 without intermixing of the striping materials as they pass from the compartments through the ducts 26, 27, 3% and 31 and through the apertures 34 in the nozzle member 33.

The striping material may be supplied to the compartments in any suitable manner such as supply pipes 35, as shown in FIGURE 6. Further, shield members 36 are secured to the central portion 12 of the stationary frame 11 and partiaily surround the upper two rolls 17 to prevent any intermixing of the striping material contained in compartments 22 and 23 with the striping material contained in compartments 24 and 25.

To rotate the feeding and pumping rolls 17, any suitable means may be provided. In FIGURE 3 suitable means are shown to be intermeshing gears 37 secured to 3 the Outer ends 20 of each of the rolls 17. These intermeshing gears 37 are driven by an intermeshing gear 38 which is driven from any suitable drive means (not shown).

As the gears 37 and 38 rotate feeding and pumping rolls 17 shown in FIGURE 6 the striping material contained in each of the compartments 22, 23, 24 and 25 will be forced down through the respective ducts 26, 27, 30 and 31 and thence through the flared openings 32 and the apertures 34 in the nozzle member 33 to apply stripes S to a traveling web of material M as it is fed from a supply roll 40, shown in FIGURE 1 into contact with the nozzle member 33 and over guide roll 41, shown in FIGURE 6. The Web of material M may be pulled from the supply roll 40 by any suitable means such as conventional feeding rolls (not shown).

To scrape the striping material from the feeding and pumping rolls 17 as they rotate to feed the striping material from compartments 22, 23, 24 and 25 down through the respective ducts 26, 27, 30 and 31, doctor blades 42 are provided. These doctor blades 42 are secured to the central portion 12 of the stationary frame 11 and are adapted to contact the surface of feeding and pumping rolls 17 to scrape off striping material as the rolls 17 rotate in the direction of the arrows in FIGURE 6. This scraping action causes pressure to build up in the compartments 22, 23, 24 and 25 aiding the feeding of the striping material through the respective ducts 26, 27, 30 and 31.

From the above description it may be seen that diflferent colors of striping material may be supplied to compartments 22, 23, 24 and 25 which are formed respectively by rolls 17, plates 21 and the stationary frame 11. The striping material is then fed from the compartments by the rotating action of feeding and pumping rolls 17 and forced by pressure down through ducts 26, 27, 30 and 31 formed in the central portion 12 of stationary frame 11. The striping material then passes into flared openings 32 formed in the bottom of the central portion 12 of stationary frame 11 from whence it passes through apertures 34 in nozzle member 33 to form a plurality of stripes S of each color of striping material on a traveling web of material M as the web of material M passes into contact with the nozzle member 33. The path of the striping material contained in each of the compartments is completely separate from the paths of the striping materials in the other compartments so that no intermixing of the colors may occur as they pass through the above described striping apparatus, thus producing a striped web of material with individually colored stripes thereon. It is to be understood that this invention has been described with apparatus containing only four separate coinpartments. However, it is within the concept of this invention to provide as many separate compartments as desired to stripe material with as many separate colors as desired.

The present invention has been described in detail above for purposes of illustration and is not intended to be limited by this description or otherwise except as defined in the appended claims.
